| guanosine triphosphate | A molecule which consists of the nitrogenous base guanine linked to the sugar ribose and which has three phosphate groups attached to the 5th carbom atom of the ribose. GTP is a high-energy compound which serves as an energy source for many biochemical reactions. It is required for the formation of peptide bonds between amino acids during translation and is required for ribonucleic acid synthesis since it is a direct precursor. (09 Oct 1997) |

| guanosine triphosphate binding protein | <protein> A type of protein embedded in the cytoplasmic membrane of the cell which transmits signals from outside the cell (such as from hormones binding to receptors on the outside of the cell) to the inside of the cell, where it causes some sort of biochemical reaction within the cell to the signal (such as the altering of metabolic pathways or gene expression). The process by which the protein does this is unclear but involves exchanging a molecule of GDP for a molecule of GTP. (09 Oct 1997) |

| guanyl cyclase | <enzyme> That is responsible for catalysing the synthesis of guanosine 3', 5' cyclic monophosphate from guanosine 5' triphosphate (cyclic GMP cGMP) is used as a second messenger in heart muscle and photoreceptor cells). Plasma membrane form of guanylate cyclase is Integral membrane proteins with an extracellular receptor for peptide hormones, a transmembrane domain, a protein kinase like domain and a guanylate cyclase domain. Examples: sea urchin receptors for speract and resact and atrial natriuretic peptide receptors. Two soluble forms of guanylate cyclase are also known they are heterodimers of highly related subunits, 70-80 kD. (18 Nov 1997) |
